Bulging Brains - Clarence The **human brain** is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size. Most of the expansion comes from the cerebral cortex, a layer of tissue that covers the surface of the forebrain. Especially expanded are the frontal lobes, which are associated with functions such as self-control, planning, reasoning, and abstract thought. The portion of the brain devoted to vision is also greatly enlarged in human beings. The brain monitors and regulates the body's actions and reactions. It continuously receives sensory information, and rapidly analyzes this data and then responds, controlling bodily actions and functions. The brainstem controls breathing, heart rate, and other processes. The neocortex is the center of higher-order thinking, learning, and memory. The cerebellum is responsible for the body's balance, posture, and the coordination of movement. In spite of the fact that it is protected by the thick bones of the skull, suspended in fluid, and isolated from the bloodstream by the blood-brain barrier , the delicate nature of the human brain makes it susceptible to many types of damage and disease. The most common forms of physical damage are closed head injuries such as a blow to the head, a stroke, or poisoning by a wide variety of chemicals that can act as neurotoxins. Infection of the brain is rare because of the barriers that protect it, but is very serious when it occurs.

__**Why Wacky? - Rachel**__ (Okay, Clarence, now, you don't have to go crazy okay?) Here, I have put on some science, confusing facts on for all of you to enjoy! - (This will probably disgust you) Most dust in your home is actually dead skin - yuk! - Although the Stegasorous was over 9 metres long, its brain was the size of a walnut - Sneezing with your eyes open is impossible - The trickiest tongue twister in the English language is apparently "Sixth sick sheik’s sixth sheep’s sick". Give it a try and see for yourself. - A hippopotamus may seem huge but it can still run faster than a man!
